Pseudo Direct Drive
Aerospace Actuator

Magnomatics have developed an ultra-light fault tolerant PDD motor for the extreme environments of a rudder flight control surface Electro-Mechanical Actuator.

​

The PDD motor has a magnetic gear at its heart which provides a unique functionality - a passively resettable torque-fuse to prevent jamming on overloads. The gear action also provides for a very low inertia system.

​

The motor is able to deliver full load torque with a failed phase-bank and each phase bank is mechanically, magnetically and thermally isolated from each other for maximum reliability and full duplex redundancy.

Advantages

  • Highest torque density​​​

  • Fault tolerant

  • Compact design

  • High reliability, low maintenance

  • Inherent torque fuse

  • Very low inertia

  • Standard power electronics
